Online Exhibitions

Where Money and History MeetLearn more about the National Numismatic Collection (NNC) through online exhibitions about topics such as: Byzantium; the coinage of Spain; he Double Eagle; life in Ancient Greece; the Coins of the Demareteion Master; outstanding U.S. rarities; Russian coins and medals; Native Americans, women, and African–Americans on early United States bank notes; and the evolution of American money.

Legendary Coins & CurrencyThis exhibition explores rare and historically significant artifacts from the National Numismatic Collection—more than half of which have never been on view, or not for many years. Coins, bills, medals, and captivating oddities—such as pattern designs, fake coins, and homemade clam shell money from the Great Depression—are on display.

As early as 1850, agitation began in Congress for the establishment of a San Francisco branch of the United States Mint. This action was blocked by people from New York-who wanted a branch in their own state-and from Georgia and Louisiana-who argued that any California operation would represent unfair competition to the branch mints in Dahlonega and New Orleans.

The opposition won, and San Francisco would go without a mint for another four years. But it did get an odd sort of hybrid, the United States Assay Office of Gold, striking an odd sort of money-a gigantic, fifty-dollar ingot that would also do duty as a coin. The arrangement was made by the Treasury Department under a contract with Moffat & Company, private assayers and gold coiners in San Francisco.

Augustus Humbert came west to oversee the operation, which got under way at the end of January 1851. For most of the next two years, Humbert's fifty-dollar "slugs" were the principal accepted currency in California. He was eventually allowed to turn his attentions to the production of smaller, and altogether more useful, coins, ten- and twenty-dollar pieces. And his operation finally laid the framework for a formal, normal branch Mint, which began the production of ordinary federal coinage in the spring of 1854.

Moffat & Company's mint, San Francisco. Obverse: Eagle with shield, fineness above. Reverse: Engine-turning with name and date in center. This was the final production of the provisional United States operation in San Francisco. A formal branch U.S. Mint was set up soon and began operations in the spring of 1854. A few proof strikes of the 1853 double eagle are known, including this coin.

United States Mint, San Francisco. Obverse: Bust of Liberty as goddess Athena facing left. She wears a crested helmet and carries a shield with the date 1915 in Roman numerals. Reverse: Owl seated on pine bough (the owl was the bird associated with Athena). On the octagonal version, there are eight small dolphins at the eight points of the octagon.

Designed by Robert Aitken, the round and octagonal coins were part of an elaborate attempt to raise money for the Panama-Pacific Exposition. That celebration was held in San Francisco between February and December, 1915. In turn, the exposition was intended to commemorate the completion and opening of the Panama Canal in the previous year. Dolphins were friendly companions of the vessels making the trip from one ocean to another, via the new Isthmian waterway.

In turn, the exposition was intended to celebrate the completion and opening of the Panama Canal in the previous year. The dolphins were on both sides of this octagonal version because they were friendly companions of the vessels making the trip from one ocean to another, via the new Isthmian waterway.

United States Mint, San Francisco. Obverse: Columbia, seated on a hippocampus, or sea horse. Reverse: Eagle facing left on what appears to be a Roman legionary standard. This and several other commemorative pieces were created at the San Francisco Mint to celebrate the opening of the Panama Canal and the exposition held in its honor. This Smithsonian specimen is the only known proof.

The sheer size of the California gold strike altered the nature of American numismatics. It was not only that mintage figures dramatically increased; the actual range of denominations increased as well.

Prior to 1849, there had been three gold coins: the quarter eagle, half eagle, and eagle (or $2.50, $5.00, and $10.00 coins). By 1854, three more had been added, a dollar, a three-dollar piece, and a double eagle, or twenty-dollar coin.

Artist James Barton Longacre designed all three of the new coins. The double eagle was the most popular. For its obverse, Longacre employed a simple head of Liberty, wearing a coronet. Stars surrounded the head of the goddess, and the date appeared below. The reverse depicted a somewhat ornate representation of an eagle, a "glory" of stars and rays above, the national motto to either side.

In 1854, the United States created a new branch mint in San Francisco to deal with the fruits of the gold rush. It was intended to replace a whole galaxy of private California mints that had created a variety of local coins.

This double eagle was the first coin the new federal mint struck. Below the eagle, each coin from the new branch Mint bore a distinctive small "S." This distinguished the coin from ones struck in Philadelphia, which had no such mark, and ones struck at New Orleans, which had an "O."
